Error ("Failure("hd")") in Modding Q&A Posted October 17, 2020 The ICT line of actions do support IF_FILE_EXISTS, but it's not really documented. The error likely means that WeiDU tried to take the first element of an empty list and it's essentially a WeiDU bug that you are getting it, since it's completely unhelpful. However, I'm not able to reproduce the problem. The code in the first post compiles without errors. If it's a better error message that is needed, I can likely take care of that without a test case, but if the error shouldn't be happening, I am going to need some code sample with which I can reproduce the problem.
